"Hello, Matt Speaking" Regardless of if it's work or personal.

I get more calls that I'll actually answer these days at work and people are passed through a switchboard to my department so know it's me they want to speak to. Back in previous work places I would answer "Priceless Shoes, Argyll Street. Matt Speaking, how may I help?". It was a direct line so our manager encouraged more info rather than just "Hello". I speak to a very small pool of people on a regular basis so they usually know who they're talking to.
